In reviewing this, I don’t see that it addresses RoHS and Ecodesign directives.
Would products in scope of these directives still require the UKCA mark by
December 2024?

Yes. If the 0 Ohm resistor needs to be adjusted to higher impedance or removed
based on experimental results, it can be done without spinning the board to
change a trace.

I'm looking into possibly getting the upgraded UL Product IQ account for my
team, and wondered if anyone had any experience with it?
If so, what of the paid features do you find the most useful?

Howdy all,
I've got a client who heard a rumor of a safety requirement for
semiconductors that entailed having some thermal cutoff. This is a
semiconductor requirement, not an end-product requirement.
Has anyone heard of this in an existing or upcoming requirement?
Thanks,
Sam

Another interesting point that can be made is I didn't say it was law, I
said List it or I won't buy it. Depending on the product (basically, if
there's a Listed competitor product on the market), you can make it happen.
In the US, often a Listing mark is enforced by marketing more than law.

OK, I've avoided jumping in on this exhausted thread, but here's my take on
the situation.
It's obvious that more than a few of the posters have not performed this
test. When you cannot answer a question with more than a theory, don't
throw it out there as fact. You muddle the knowledge pool.

As far as differences go, if you purchase the standard (www.comm-2000.com)
